                    <h2>洒水车水泵压力小怎么办</h2>
                </div>
                <div class="body">
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 一、洒水车管道过滤网堵塞了，因为洒水车水泵抽进去的水不可能全部是干净的自来水，可能是脏水池或是池塘里抽的水，那样水里杂质太多，过滤网容易被杂物堵住了，如沙石、塑料袋、树枝等杂物，只需要把过滤网三通内的过滤网拆下来清洗干净，确保畅通，</span><span
                            style="font-size: 14px;">即可恢复正常的工作，过滤网的位置在洒水车水泵进水口管道中端。&nbsp;</span></div>
                    <div>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 二、叶轮出现磨损变形，导致洒水泵叶轮正常旋转但无法正常进出水，只需更换新叶轮即可。&nbsp;</span>
                        <iframe id="tmp_downloadhelper_iframe" style="display: none;"></iframe>
                    </div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp;&nbsp;</span></div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 三、水泵密封出现缝隙，导致空气进入，洒水泵压力不足，解决方法是仔细检查工作中的水泵是否有缝隙泄露水。&nbsp;</span>
                    </div>
                    <div>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 四、洒水车水泵泵内无水工作，导致水泵内机械密封出现无水干烧的现象，更换机械密封即可。&nbsp;</span>
                    </div>
                    <div>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 五、传动轴功率不足，使得水泵内叶轮未达到正常工作转速，加大油门即可。</span></div>
                    <div>
                        &nbsp;</div>
                    <div>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">为保证泵具有良好的自吸性能，必须满足以下条件：&nbsp;</span></div>
                    <div>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 1、泵工作前，泵内的液体存量必须高于泵轴，因此泵进口处必须接一个向上弯的弯管再接一个水平管和快速接头，快速接头中心线必须高于泵轴中心线300毫米。&nbsp;</span>
                    </div>
                    <div>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 2、进口管路系统必须保证不漏气，密封性能完好。&nbsp;</span></div>
                    <div>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 3、吸水管的吸入头必须浸没于水下，以免空气吸入水管。&nbsp;</span></div>
                    <div>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 4、出口管道与泵出口连接时必须保证直管长度≥200毫米后再接弯管。&nbsp;</span><br>
                        &nbsp;</div>
                    <div>
                        <span style="font-size:14px;">&nbsp; &nbsp; 5、进水口管道中端必须有过滤网三通，保证水进入水泵前不会有杂质损坏泵内精密部件。</span>
                    </div>
